| Abstract | Several sets of lightly n-doped silicon wafers were implanted with indium at an energy of 70 keV and a dose. of 5.8 Ø $10^{14}$ $cm^{-2}.$ Carbon was subsequently co-implanted with an energy of 13.5 keV at doses ranging from 0 to $2.22Ø10^{15}$ $cm^{-2}$ to achieve a carbon distribution overlapping the indium one with ratio of peak concentration ranging from 0 to 2. The samples were annealed at temperatures of 650 to 1100°C for times between 0 dwell and 1 hour in flowing $N_{2}.$ Following annealing electrical characterization of the samples was performed via four-point probe and Hall effect measurements to achieve information about sheet resistance $(ρ_{s}),$ Hall mobility and sheet carrier concentration $(N_{S}).$ The retained dose and lattice site location of the In have been investigated using Rutherford backscattering spectrometry (RBS). Secondary Ion Mass Spectroscopy (SIMS) was performed to measure the atomic doping profiles in the samples. The results show that the electrical activation of the layer increases with increasing carbon concentration. Increasing the annealing temperature and/or time results in a deactivation of the implant. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
